Abstract

Un circuito amplificador de potencia (300) con ajuste del suministro para el control de la potencia de los canales adyacente y alterno. Un amplificador de potencia (172) amplifica una senal de entrada con el objeto de producir una senal amplificada. Un detector de pico a promedio (180) detecta los niveles pico de la senal amplificada y un nivel promedio de la senal amplificada y produce una indicacion de los niveles pico y el nivel promedio. Un controlador (181) ajusta un voltaje de suministro al amplificador de potencia (172) en respuesta a la indicacion para causar que disminuya el voltaje de suministro conforme aumenta una diferencia entre los niveles pico y el nivel promedio arriba de un nivel previamente determinado y para causar que se eleve el voltaje de suministro conforme disminuye la diferencia abajo del nivel previamente determinado.
